If a paper discussion is to take place, the Virtual Chair venue has provided two areas in the main lobby where participants can congregate. The rug areas will be clearly marked with signs. To join the discussion, navigate your avatar onto the rug where you will hear and see only those other participants in the discussion.
If your avatar is unable to access the rug becuase it is being blocked by another avatar, hold down the G key to move through the other avatars.
